We’re all familiar with the AISC metric for PM miners which had me thinking about the same for Bitcoin.

From 2021 but still relevant today.  The True Cost Of Bitcoin

BTC Average Mining Costs  << of course halvings will cause these to rise w/ more (mostly fossil fuel) energy to create the same unit of BTC.

Bitcoin Energy Consumption in tWh

Also BTC won’t stop halving until around 2140 (no one currently living will witness this).  IMO – quite literally a ‘waste of energy’ not to mention having aspects of a Ponzi scheme – success of early adopters dependent on new recruits.
